MAX17262 Plug-and-Play Battery Fuel Gauging and ModelGauge m5 EZ 

The MAX17262 is an ultra-low power fuel-gauge IC which implements the Maxim ModelGauge™ m5 algorithm.

The MAX17262 monitors a single cell battery pack with integrated internal current sensing for up to 3.1A pulse current. The IC monitors a single-cell battery pack and supports internal current sensing for up to 3.1A pulse current. The IC provides best performance for batteries with 100mAhr to 6Ahr capacity.

The ModelGauge m5 EZ makes fuel-gauge implementation easy by eliminating battery characterization requirements and simplifying host software interaction.
The ModelGauge m5 EZ robust algorithm provides tolerance against battery diversity for most lithium batteries and applications.
